President Trump has awarded U.S. Space Command to Huntsville, Alabama, in a move that several Pentagon insiders and lawmakers say bypassed the military’s top pick of Colorado Springs, the unit’s current home, because of political considerations.

It’s a decision that Colorado lawmakers say they will ask President-elect Joe Biden to overturn and has caused Colorado Springs Republican Rep. Doug Lamborn, a Trump loyalist, to break with the administration. The move also will likely kick off a congressional investigation into how the decision was reached.
